This is just a basic MSSQL template. It checks if the SQL Server and SQL Server Agent service is running. It also checks if the server is listening on port 1433.
1. Once this template is imported they just need to modify the 2 Windows Service Monitor components.
2. In that expanded list find the Net Service Name. You'll just need to replace the highlighted part with the name of your SQL instance.
You can find your SQL instance name by simply looking in windows services. The SQL instance name is in parentheses.
